I have lots of memories in my life time that are triggered by aromas of specific things unique to that time. Certain kinds of wood burning ,bring me back to camping with dad and certain trips we've taken. the smell of a particular cigar takes me back to when I was 4 -5 years old in a public park picnic at nigh amongst a bunch of strangers . I wasn't afraid it was just an adventure for me . The smell of a truck stop reminds me of hitch hiking across country when I was 18 , off to see the world. the smell of fresh cut pine boards takes me back to dads cabinet shop behind the garage .saw dust every where. Some times a woman will pass by wearing sent my wife use to use when we met , ahh the memories.
